SPEGIFLCATION forming part of vlv'aetters Patent No. 702,647, `dated.'urielli,` 1902.

Application filed Augn st 21,

To @ZZ whom it may concern:

Be it known that I, WILLIAM G. HALL, a citizen of the United States,residing at Grafton, inthe county of Taylorand State of West Virginia,have invented a new and useful' Plow Attachment, of which the followingVis a specification. i f i This invention relates to plo ws, and has forits object to facilitate the operation thereof when plowing throughgreen forage-as, for instance, grass, corn or cotton stalks, and thelike-and to provide for cutting such vegetation immediately in advanceof the plow, so that the latter may not become clogged by the vegetationand in order that the latter may be conveniently turned over into theground to rot, and thereby fertilize the soil.

It is furthermore designed to provide for conveniently applying thepresent invention to the beam of an ordinary plow4 without changing oraltering thesame and also to arrange for operating the' cuttingmechanism from the ground-wheel, whichis ordinarily carried at theforward end 0f they plow-beam.

Withthese and othervobjects in view the present invention consists inthe vcombination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims withoutdeparting from the spirit or sacrificing anyof the advantages of the invention. 'j

In the drawings, Figure 1 isa perspective view of a plow having thepresent invention applied thereto. Fig. 2 is a transverse sectionalview. Fig. 3 is a detail side elevation.

Like characters of reference designate corresponding parts in all thefigures of the drawings.

Referring to the accompanying drawings, 1 designates an ordinaryplow-beam, which carries any common form of 'plow 2 and is ing-wheel 3for contact with' the ground. These parts are common and Well known andhave been shown merely to illustrate the application and operation ofthe present invention.

yper end of the cutter-bar.

In carrying out the invention there is pro- SerialNo. 72,831.(Normodel.) u

vided an uprighty hanger 4t, which is hung from theland-side face oftheplow-beam and alined above the point of. the plow. To the inner side ofthis hanger there is secured a plurality of forwardly-directedguard-fingers 5, similar `to those employed in the cutting apparatusfofa mowing-machine, and to the outer side vvof this hanger there issecured la guide-baro, havinga plurality of forwardlydirected lugs orprojections 7, which coperate with the ngers to form a guideway for avertically reciprocatory cutter-bar 8, which has the usualtriangular.cutter-blades, as commonly employed` in mowingmachines. Apointed foot or shoe 9 is carried by the lower end of the hanger and isprojected forwardly therefrom, soI asto lieiu'vertical alinementwithrythe point ofl the plow. Rising from thetop ofy the'beam and alinedvertically with the hangeris a standard 10, which is providednear..itslower end with a laterally-projectedspindle 11, upon which is mounteda sprocket-wheel12, that is designed to be drivenby means of asprocket-chain 13, travelingover a sprocket-wheel 14, carried by androtating with the ground-'wheel 3. Upon the outer end of thespindle 11and rotatable therewith there is .provided a gear-wheel l5, which is inmeshwith an upper pinion 16, that is carried bythe adjacent end of aspindle 17, whichis projected in opposite directions through .the .upperend portion ofthe standard and carries upon its opposite end a crankdisk18.;l Motion' is transmitted" from the crank-diskito the,l reciprocatorycutter-bar by meansof a linker pitman 19, which has one end providedwitha wrist-pin connection 2O with thecrank-disk and its opposite endhavinga loose or wrist connection 21 with the up- In the operation ofthe manipulated as usual, whereby the groundwheel is rotated, andthrough the medium of the sprocket-wheel,theintermeshed,gearsand thepitman connection thecuttor-bar` is Vreciprocated in a verticaldirection, thereby to cut the grass or other vegetation 4throughwhichthe plow is being worked. As the cutting apparatus is located just infront of the plow, it cuts the vegetation, so as to open a path for theplow, and thereby prevent the vegetation from hanging upon and cloggingor obdevice Athe plow is structing the passage of the plow; also, as thevegetation is severed and loosened it can be readily turned aside'by themoldboard, so as to eifectually turn the cut grass or the like into theground for the purpose of fertilizing the latter by the rotting of thevegetation.

From the foregoing description it is apparent that no change oralteration is required in an ordinary plow for the application ofthepresent invention, and when applied it does not interfere with the usualmanipulation of the plow, but, on the other hand, materially facilitatesthe working of the plow through long or high vegetation.

It is desired to call particular attention to the fact that the pointedfoot or shoe 9 has its forward end located at or projected slightlybeyond the extreme forward end of the plowpoint, and the active portionsof the cutterblades Work in a vertical plane slightly in advance of thepoint where the front cutting edge of the plow-point begins to rise, soas to cut the grass or the like slightly in advance of the plow-point,thereby to separate the grass and give unobstructed passage for theplow-point. Hence the plow-point does not engage with the uncut grass,and thus considerable strain and friction is removed from the plow.

What I claim is'- l. The combination with a plow-beam, and a plowcarried thereby, of means for cutting vegetation located in advance ofthe plowpoint with a space between the cutting means and the plow-pointthereby to form an unobstructed passage through the vegetation for saidplow-point.

2. The combination with a plow-beam having a plow, and a ground-wheel,of a vertically-reciprocatory cutting apparatus hung from the beam andalined in advance ot' the plow-point, with a space between the latterand the cutting apparatus and means for operating the cutting apparatusfrom the ground-wheel.

The combination with a plow-beam having a plow, and a ground-wheel, of ahanger hung from the beam and alined in advance of the plow-point,apendent fingered barcarried by the hanger and provided at its lower endwith a forwardly-projected shoe having a downwardly-inclined sharpenedfront end portion extended in front of the bar, avertically-reciprocatory cutter-bar mounted upon the hanger in rear ofthe shoe and coperating with the ngers, there being an open spacebetween the cutting apparatus and the plow-point, and means for workingthe cutter-bar from the ground-wheel.

Ll. The combination with a plow-beam having a plow, and a ground-wheel,of a vertically-reciprocatory cutting apparatus hung from the beam infront of the plow-point, with i an open space between the latter and thecutting apparatus a sprocket-wheel mounted upon the beam, anothersprocket-wheel carried by the ground-wheel, a sprocket-chain connectingthe two sprocket-wheels, a gear in Operative relation to the rirstmentioned sprocket-wheel, a crank-disk driven from the gear, and apitman connection between the disk and the cutting apparatus.

5. The combination with a plow-beam having a plow, and a ground-wheel,of a hanger hung from the standard and alined in front of theplow-point, a forwardly-directed foot or shoe carried by the lower endof the hanger and located above the forward end of the plow-point, areciprocatory cutter-bar mounted upon the hanger, a standard rising fromthe beam, a gear-wheel mounted upon the standard and in operativerelation to the ground-wheel, a spindle carried by the upper end of thestandard and projected at opposite sides thereof, a pinion carried byone end of the spindle and in mesh with the gearwheel, a crank carriedby the opposite end of the spindle, and a pitman connection between thecrank and the cutting apparatus.

t3. A plow attachment, comprising an upright hanger having means forconnection with a plow-beam, and also provided with a forwardly-directedshoe at its lower end, forwardly-projected guard-lingers carried by thehanger, a vertically-reciprocatory cutter-bar mounted upon the hangerand in operative relation to the fingers, the cutting apparatusincluding the shoe being disposed for arrangement in front of theplow-point so as to have a clear space between the cutting apparatus andthe plow, a standard havingits foot provided with means for attachmentto a plowbeam, a lower transverse spindle carried by the standard, anupper spindle carried by and projected at opposite sides of thestandard, a drive-wheel mounted upon the lower spindle, means foroperating the drive-wheel from the ground-wheel of a plow, a gearcarried bythe lower spindle, a pinion carried by one end ofthe upperspindle,a crank at the 0pposite end of said spindle, and a pitmanconnection between the crank and the cutter-bar.

7. The combination with a plow-beam having a plow, of avertically-reciprocatory cutting apparatus hung from the beam and alinedin advance of the plow-point, with a clear space between the latter andthe cutting apparatus and means for operating the cutting apparatus.

In testimony that I claim the foregoing as my own I have hereto aftixedmy signature in the presence of two witnesses.
